产品描述（Product Details）
This product is an IgG-specific endoglycosidase hydrolyzing complex N-glycans at the Fc N-glycosylation sites. It is derived from Streptococcus pyogenes and expressed in E. coli. The enzyme contains a His-tag and the molecular weight is 110 kDa.The enzyme deglycosylates IgG after the core GlcNAc and display limited activity on high-mannose and hybrid-type glycans.
应用说明（Application）
Endo S2 is specific for N-glycans attached on the Fc-domain of IgGs, and hydrolyzes Fc-glycans of all human IgG subclasses and IgG from many other species, including mouse, rat, monkey, sheep, goat, cow, and horse.
单位定义（Unit Definition）
